If your BlackBerry Z10, Q10, Z30, Q5 or P'9982 has been updated to BlackBerry OS 10.2.1 or higher, you can now install Android apps directly onto the phone. Here's how!
BlackBerry 10.2.1 introduced the ability to install .APK files, which are the app files used in Android, directly to your phone. This throws the doors open to install a wide variety of Android apps on your BlackBerry 10 device, be it a Z10, Q10, Q5, Z30, or anything else. This used to be possible through a long, convoluted process, but it's much easier now. Basically, if you can't find an app in BlackBerry World, odds are there are other sources for your favorite app.

Step 1: Find your APK
Here is few sources you can count on
Step 2: Get the APK file on your BlackBerry
You can get an Android APK install file on your BlackBerry by visiting
the source in your BlackBerry browser (which is the easiest option),
e-mailing yourself the file, or moving the file directly from your
computer to your phone by plugging them together with a USB cable.
Step 3: Install the APK file from your BlackBerry
If you downloaded the APK from your browser, the Downloads window should
have already popped up asking you where you want to save it and what
the filename should be; just tap the file when it's done. If the
download window isn't there, it's easy enough to get back up. Tap the
overflow menu button in the bottom-right (three little dots), and tap
Downloads.
Your Android app should start installing after a short "Processing"
indicator. Tap the Install button in the top right, and tap Accept on
the pop-up window which informs you of the device permissions that are
required for the app to run.
